SHINGLEA,

Application filed December 26, 1924. Serial No. 758,077.

This invention relates to shingles for roofing purposes. One object of the invention is to provide shingles which can be laid on the roof in such a manner as to present an improved appearance. Another object is to form the shingles, and to lay them on the roof, so as to lock down the exposed portions of the shingles and thus to prevent them from turning upwardly and exposing the roof to the elements, and affecting the appearance of the roof. Another object is to provide shingles so formed that they can be laid on the roof with a minimum amount I the corners 12 and 13 of the positionin single shingle; and Fig. 4 is a plan view of.

a modified form of shingle.

The general shape of these shingles is that of a parallelogram, and in this particular instance the shingles are substantially square-shaped, it being understood however,

that the general shape of the shingle may be varied as desired, and that the appearance of the roof will be varied accordingly. Each of the shingles compr ses a projection 5 on one corner and a projection 6 on the opposite corner. These projections are so formed that when the shingles are laid on the roof the outer edges of these projections are brought into contact, and the corners 7 and 8 are brought into registery, so that the edges 9 and 10 fall in the same horizontal line. This registering of the outer edges of the projections provide means for properly the shingles in the same row; and the s ingles of the adjacent overlying row are placed so that the corners 11 of the overlying shingles register respectively with adjacent underlying shingles.

In order to lock the-exposed portions 14 down, I provide a locking means in each of these portions, such as the tongue 15 which is formed integral with the shingle by cutting therein slits 16. This tongue is bent downwardly and slipped under the adjacent edges 9 and 10 of the two underlying shingles. These tongues not only lock the lower corners of the shingles down, but also assist in positioning the shingles when they are placed on the roof, as it is necessary onl to slip the tongue under the edges 9 anc 10 and pull the upper shingle upwardly as far as it will go. This of itself brings the corners 11 in registery with the corners 12 and 13.

By this arrangement it will be seen by the dotted lines of Fig. 2 that a material lap is provided for, and that. a dependable and efl'ective covering is producedwithout unnecessary'lapping of the shingles.

A modified form of shingle is shown in Fig. 4. This shingle has a projection which has an edge 21under which is slipped the tongue of the overlying shingle; thus eliminating the somewhat exposed joint which is formed by the other type of shingle. With the assembled shingles of Fig. 1, the edges are exposed and lap over the edges 21.

I claim as my invention:

1. A shingle, two of the opposite corner portions of said shingle having a straight edges, each of which form substantially equal angles with the adjacent sides and each of said corner portions having an edge projecting inwardly and at right angles to said corner edge, and an interior tongue fixed to said shingle adjacent a third corner, and adapt-ed to pass under the said projecting edges of two adjacent shingles.

2. A shingle having corner portions, two of the opposite corner portions having straight edges, each of which form substantially equal angles with the adjacent sides, and each of said corner portions having an edge projecting inwardly and at right angles to said corner edge; and a tongue fixed to a third corner portion but spaced inwardly fromthe edges of the shingle, adapted to lie under the said right angled edges of two underlying shingles.

3. A shingle having four edges substantially at right angles to each other, two of the opposite corner portions having recesses with short edges at substantially 45 degrees to the adjacent main edges, and a third corinwardly from the edges of the shingle, and adapted to lie under the two short edges .of the adjacent underlying abutting shingles.

4. A shingle forming substantially a parallelogram and having at one corner a projection extending beyond the outline of the her having a tongue fixed thereto but spaced parallelogram, and an adjacent recess Within the said outline, and a tongue fixed to an adjacent corner but spaced inwardly from the edges thereof, said tongue being adapted to lie under the edge formed by the said projection and recess of an adjacent underlying shingle.

5. A shingle forming substantially a parallelogram and having at one corner a projection, and an adjacent recess, said recess having an edge which is a continuation of one of the edges of said'projection, and said recess being Wthin the outline of said parallelogram, and a tongue fixed to an adjacent corner but spaced lnwa-rdly from the edges thereof, and adapted to lie under the said edges of an adjacent underlying shingle.

6. A shingle forming substantially aparallelogram and having at each of two'opposite corners a projection extending beyond the outlines of the parallelogram, and an adjacent recess within said outline, and a tongue fixed to an intermediate corner but spaced inwardly from the edges thereof, and

adapted to lie underthe edges of two of said projections which are adjacent, and registering projections of the underlying shingles.

In testimony whereof, I hereunto set my hand.
